Power wringers are commonly provided with release devices and are also' provided'with some means for resetting pressure after release has been efiected; .Ordinarily'the resetting] device retains the pressure of the rolls after the resettingythe release device also retaining pressure and operating either directly on the resetting device or independently thereof; In the present invention the resettingdevice is relieved of pressure after the pressure is set, the release device taking on the pressure. yolves'the arrangement of the resetting and releasedevice at the same end of the wringer, also an improved'release device. Features and de-' tails of the invention will appear from the specificationand claims. 7

modification of Figs. 4 and. 5 having, however;

. similar features to the latch member of Fig. 1,

roll having a shaft l. The shaft 5'is iournaled in bearings 8' nounted at .thelower end of the stile and actuated by any suitable power device (not shown) forms a driving means for the wringer rolls. The shaft 1 is journaled in'bearings 9 1 slidinglymountedin the upperend of the stile. A spring Ill engages the upper bearings and forms the pressure means, the adjustment of the spring being accomplished by a screw ll operating through a fitting lla on the top bar I2. 'The top bar I2 is detachably locked with'the stile 3' 'by, the interlocking shoulders l3 and [4 on the stile and end'of the top bar respectively.

; A latch member s has the two'sides extending downwardly intothe stile' 2. A pin lliextends t u h; the i t bar and side, plat s vo a The invention also in-' connecting the latch member with the top'bar; The plates'are connected by the cross piece I! across the top, of'the latch member.- Each'of the side plates has a slot l8 with anoffset' I9. At 'locking-meanslll which is preferably in the form o'f'pin'se gtending through the walls of the stile 'extend through-the slots. When the means is the offset-portion 19 it is adapted to lock the top bar*withth'e' stile. The latch member is releasably heldin this set position by trip mem- 1? ber-2 li The trip member 2| ispivotally mounted 1-30 Figj'l shows a latch member as used in the in the top barby a-pin 22, A lip 29 of'tlie trip member extends over thecross'plate I1 and locks the latch-member in set position.' When the lip 23 is lifted bythe depression of the outer end of the trip member this releases the latch member and the pressureof the spring l0 cams the latch member o'litfof thefofiset' portion I9 oi the slot, and the-slot I8 permits the-upward or free movemerit-of the latch member in the stile, thus permitting thefend of the top-bar to swing up to release pressure'on the rolls. This upward movement'jof the release end-of the topbar disengages the interlocking shoulders 13 and i4 so'that the entiretop bar is released thus providing further freedom for jthe'rolls. I

*Ther'esetting mechanism comprises a toggle lever,-'a"link- 24 of the lever being channel formed straddling'th'e top 'bar and; the side stiles. It is pivotally-connected by apin 25 with the end of the top bar." The other li'nk 26' of the toggle lever is pivotally connected by a pin 21 with the upper end of the stile. This link has a slot 28 with arr-offset 29, the oifset being an elbow forming a projection at ;on the link 26. A pin 3| passsthrough thes'ide'walls of the link 24 and through the slot 28. As the toggle approaches the bottom orclosed-position,- the link 26 is stopped so that with the final movement of the link 24 the pin 3| is carriedout'of-the offset 29 andinto' register'with-the slot 28. A spring 39a yieldingly holds the-link'26 so as to' retain the pin 3| in the oifset during the setting-operation'as indicated in Fig.2. As the link 24 approaches its set position the-spring passes off theprojection 30 andthus permits the stopping of the link 26 and permits the parts to retain-their position close to the stile through gravity alone.

In the operation of the device, starting with the parts in set position, a release is accomplished by depressing the trip member 21 and releasing downwardly effecting a resetting pressure on the spring. As the link reaches its lower position the latch member l5 reaches a position bringing the pin 20 opposite the offset*l9'-and the camming action of the upper wall of-the offset swings the link sidewise carrying the pin 20 into the offset and the upper end of the plate ll out from under V the lip 23, thus permitting the trip member to move downwardly into set position. Preferably-'- a spring 2 la is arranged between the latch member 15 and the trip member 21, this spring yieldingly tending to reset the trip member and th latch member.

v H H e In the modification shown in Figs. 4,5 and 6, the wringer and the release mechanism are similar to the wringer and release mechanism shown in Figs. 1, 2, 3 and in Figs. 7 and 8, except the sides of the bearing blocks extend below the shaft 1. The latch member |5a is not connected at the bottom as is the latch member [5 in Fig. l, and the top of the wringer in Figs. 4,5 and 8 is notched at 2a to give clearance for the pivot pins 20. The resetting mechanism comprises a toggle lever operating between the frame and the top bar. A link 32 of the toggle lever is piv; otally connected at-33 with the top bar. A link 34 is in the form of a wirebail, the ends of the bail being pivotally connected at 35 with the link 32., A cross member 34a of the bail extends through a strap 36 which is secured to the face of the side stil 2 providing a slot36a between the face of the stile and the strap. Theaupper end of the strap forms a shoulderf'l which is adapted to limit the upward movement of the cross member 34a of the bail. T o;reset the wringer,
